int_T ssSetOutputPortVectorDimension(SimStruct *S, int_T port, int_T w)
SimStruct representing an S-Function block.
Index of an output port.
Width of the vector or DYNAMICALLY_SIZED.
1 if successful; otherwise, 0.
Specifies that port emits a w-element vector signal. If the width is dynamically sized, the S-function must provide mdlSetOutputPortDimensionInfo and mdlSetDefaultPortDimensionInfo methods to enable the signal dimensions to be set correctly during signal propagation.
C, C++
The following example specifies that output port 0 emits an 8-element matrix signal.
ssSetOutputPortVectorDimension(S, 0, 8);
See the S-function sdotproduct.c used in sfcndemo_sdotproduct.mdl for a complete example that uses this function.
